This invention relates tosmoking pipesand ,the W object thereof is to provide a smoking, pipe equipped so that the influx :6! air into the bowl;

the

shank and therethrough; .is divided and forced into. controlled multiple channelslof draft, thereby eliminating theigathering of moisture at the l 'e P rtion of theshank. The invention, together {with its objects and advantages, willbe best understood from a study of, the following description taken in connection with theaccompanying drawing, ingwhich like 7 A characters of reierencewhavebeen employed in todesignate identical parts and wherein:

Referring nowin detaii'to the several figures, the pipeproper, as shownin Figurel is composed oi five elements. I l, i

Thetpipe may be constructed fromxany pre-' ierredmaterial or i'roma combinationof: such Thebowi lXFigure l) is iormedjaste. separate element: its major upper portion extending upf wardly from the top; edge margin of a cavity in the enlarged, bowl-end portion of the shank 2, v the other end, the mouthpiece end, oiwhich is adapted for engagement withxthe inner end oi' the mouth piecel.

The minor lower portion-of -the, bowl 1 is iladapted to be housed in spaced relation to the floor ofjthecavityin thebowl-end of the shank 2.

Theconstruction employed forthe; engagement ofthebowli withthe shank 2 is=optional .Any one of numerous well known means :iorw such connections. in fixedly attached I or. in removable relation of the bowlto the shank maybe em fployed. i

The cavity 4 is bored in the major upper, to-

eter of this cavity is varied to coniormto the size and the style of the pipe designed and also has its. depth from the top edge margin down passage thereof therethrough and into the ,bottom ofthe mass of tobacco in the bowl of the pipe and'also greatlysreducing the tempera ture of thesrnoka'hy forcin same into contact with the surfaces-oi multiple channels in the I Through the oi-the bowl I are let the perforations 8-9i0 :(Fikurej 2). These perforations are specifically I located and spaced for cooperative relation with i the termini of conduits in the stern-forming portion oitheshank 2. The perforation 8 extends downwardly from a point'below and adjacent to established by these factors. From this pointjof depth cavity 4 is continued downwardly, at a lesser diameter, thus tormingthe cavity 5 inthe minor lower, tobacco-free portion otthe bowl.

This operationcreates the annular, inwardly extending shoulder a. This shoulder functions as a support tor an annular screen diaphragm} which covers the cavity 5 nd forms flOOr for thecavityl; W i

11001 of the minor lower portion the inner edge of the annular shoulder 6 and on a linewiththemedial portion of the floor oi the cavity 5, and the"perforations 9 -10 respectively,

are located one'oneach side of and adjacent to this medial line and are in similarrelation to the annular shoulder 6 on the side wall of this cavity that is opposite to thefperioration 8. The spac- (ing of the perforations 8,9l0 is'designed to comewithin' the circumference of the diameter 1 a of the flooroi the cavitydn the bowl-end of the shank for cooperation with the termini of conduits in the stem-forming portionot this shank.

I The bowl-end of the shank. 2 has acavity therein ,which is ada'ptedfor housing the'minor lower wall of the bore.

portion of the bowl I with the. under surface thereof. being in, spacedrelatiomto' the floor oi cavity, and also for holding, intermediate ,said under face and 'in closely spaced relation thereto, and the above mentioned floor surface Q the end portion oia'shank element. The'bore in the stem-forming portion or the shank Z is dimensioned "to, receive the shank element and holdisame in snug engagement with the inner e numeral ll (Figure 3) designates this shank element; its longitudinaldi'niension equals,

or may, totaminorextent, exceed the space intermediate-the mouth-piece-end margin of the shank 2 and the far wallof the cavity vin the bowl-end thereof. fInto the side portionsioi the 1periphery or the shank element It and parallel to its longitudinal axi grooved channels are let and into oneoi the spaces of the periphery, in-

t containing portion of the bowl. The diamtermediate these grooved channels and on the medial line or this, space another such like grooved channel is let.

cutaway portion I3a is formedwithits contour similar to the lower inner portion of the bowl of a pipe. The lowest point in .this cutaway portion" coincides with a transverse line from grooved channel 9a to the grooved channel Ilia. The under face of the end I3 and of the cutaway portion I311 is adapted for contacting engagement of the cavity in the bowl-end of the shank 2.

They pipe is assembled as follows: the annular screen diaphragm I is entered into the cavity 4 and forced to its seat on the annular shoulder 6. The minor lowerportion of the bowl I is placed into the cavity in the bowl-end of the shank 2 with the perforation 8 above the opening of the bore of the stem into the bowl-end cavity of the shank 2 and in line with thelongitudinal center.

thereof. The shank element II the end J3 foremost and cutaway portion I3a uppermost is entered into the boreof the stem-forming portion of the shank 2 and brought inwardly to abut the end l3 against the lower portion of the I far wall of the cavity in the bowl-end of the shank. The mouth piece 3 which has its inner end portion adapted to house the pin I2a is attached by means of any of the well known methods for such engagements.

In thisassemblythe grooved channels Biz-9a;- I Ila are in cooperation with the inner wall of the bore of the stem-forming portion of the shank 2 and thus form conduits through this stem. The bowl-end termini of these conduits lie in spaced, staggered relation to each other in the cutaway portion I31; and under and in closely spaced relation to and in substantial alignment with the perforations 89III, respectively, in the floor of the minor lower portion of the bowl I. This relative position of the elements of the pipe to I each other and of the termini of the conduit 8a to and central suction draft normally force such concentration of it.

Thaforcing of the smoke through the conduits 8c9a=-I0a in the stem-forming portion of the shank 2 also aids the cooling thereof, and results in a more comfortable use of the pipe.

While I have herein illustrated what I'believe to be a preferred and practical embodiment of my invention, it is obvious-that various changes 10 and alterations might be made inv the general details set forth but consider myself at liberty 5 to make such changes and alterations as fairly with the floor and the lower inner wall portion fall within the spirit and scope of the appended claims.

I claim:

1. In a pipe, comprising a separate bowl, a

shank and a mouth piece, one'end of the shank engagement with thebowl in fixedly attached or removable relation therewith, said bowl having an open major portion, a, cavity therein of a given diameter and having integral therewith a closed end minor lower portion, a cavity therein being an extension, at a lesser diameter, of the cavity in said major upper portion of said bowl, an inwardly extending annular shoulder intermediate said cavities, this shoulder being adapted for supporting an annular diaphragm, an annular diaphragm on said shoulder forming a floorv for the cavity in said major upper portion and a cover for the cavity in said minor lower portion ofthe bowl of the pipe, the closed end margin of the minor lower portion-having let through its floor 40 portion specifically located and spaced perforations and said minor lower portion being adapted u for being housed in the enlarged end portion of the shank and an element in the shank havin a cutaway portion adapted to lie in the bowl end of the shank andconduits extending longitudinally of the element, terminating in said cutaway portion, the under face of the closed end of the bowl being closely spaced relative to the upper face of said cutaway portion and the 5 perforations therein being in closely spaced re-;

lation and in substantial alignment with the terthe perforation 8 and the conduit 9a to the perforationl and the conduit "late the perforation I0 is accomplished when the bowl I is positioned ontheshank 2. If a detachable junction of these two elements is desired, a stop point is 5 provided which prevents the displacement of the bowl I, either, when the pipe is assembled or by accidental displacement after being assembled.

It will be observed that, in a pipe constructed as herein described, when suction is applied at the mouth piece 3 to ignite the'tobacco contained in the upper portion of the bowl I, the strongest influx of'air thereinto is forced by this suction to points on. the mass of the tobacco in the bowl produced. 'The normal burning of tobacco being I by means of glowing coals, the-coals, followin the strongest line of draft downwardly trap moisture intermediate said lines of burning coals and dry same as condensation occurs. This mini of complementary conduits in the shank N of the pipe.
